In Schizosaccharomyces pombe, transcripts derived from the pericentromeric dg and dh repeats promote heterochromatin formation via as well as an mechanism involving the RNA polymerase II (RNAPII)-associated RNA-binding protein Seb1 and RNA processing activities. We show that Seb1 promotes long-lived RNAPII pauses at pericentromeric repeat regions and that their presence correlates with the heterochromatin-triggering activities of the corresponding dg and dh DNA fragments. Globally increasing RNAPII stalling by other means induces the formation of novel large ectopic heterochromatin domains. Such ectopic heterochromatin occurs even in cells lacking These results uncover Seb1-mediated polymerase stalling as a signal necessary for heterochromatin nucleation.
